Title: Ball dispenser unit control device for pachinko machine
Inventor: KANESHIRO SHUZO
IPC: A63F7/02
Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To feed pachinko balls from a ball dispenser unit only in a normal game mode by applying the constitution that a valuable game element lending prohibition signal is outputted to the ball dispenser unit, concurrently with the receipt of a valuable game element lending signal, and also a valuable game element lending permission signal is outputted to the ball dispenser unit when the number of current valuable game elements is equal to or less than the preset value. SOLUTION: A control device 14 makes judgement as to whether an inputted signal is sent from a pachinko (Japanese pinball game) machine 4 or from a ball dispenser unit 1, and processes the signal on the basis of the result of the judgement. When the signal is identified as a ball lending signal from the ball dispenser unit 1, the control device 14 outputs a ball lending prohibition signal (e) as well as a card takeout prohibition signal (f) to the ball dispenser unit 1, so as to stop a subsequent ball feed and prohibit the return of a card. Furthermore, the control device 14 performs a timer process, and identifies the card as discharged, upon the elapse of a time counted with a timer or the receipt of a game-over signal (d). A ball lending permission signal (g) is subsequently outputted from the control device 14.  Also, the control device 14 calculates a current ball number on the basis of a shot ball number signal (a) and a feed ball number signal (b) from the pachinko game machine 4, and outputs a ball lending permission signal (g) to the ball dispenser unit 1, when the current ball number becomes equal to or less than the preset value. Thus, it is possible to prevent the occurrence. of the fraudulence.

Title: Controller for internal-combustion engine
Inventor: KONDOU JIYUNICHI
IPC: F02D29/02
Filed: 1982-04-03
Abstract: PURPOSE:To restrict the variations in rotating speed, by a method wherein a load quantity depending on a vane pitch and a steering angle is impressed as a preceding signal for controlling fuel quantity on a fuel control signal system utilizing the variation in the rotating speed. CONSTITUTION:A steering angle-load function generator 2 reduces an increase in load due to a steering operation to an increase in fuel quantity, and outputs 14 the latter increase. A vane pitch-load function generator 5 outputs a fuel signal 11 corresponding to the vane pitch. Accordingly, the variations in the rotation is reduced and controllability is enhanced, by a method wherein the load quantity depending on the vane pitch and the steering angle is impressed as the preceding signal for controlling fuel quantity on the fuel control signal system utilizing the variation in the rotating speed. In addition, when a signal indicating an increase in load is generated, calculations can be conducted whereby a fuel quantity limit (a conventional limit generally used) used in a continuous operation is increased to a transient momentary allowable limit to thereby feed a large quantity of the fuel and make the most of the main function.
